Hillary Clinton says she's open to supporting a constitutional amendment to overturn the Supreme Court’s 2010 ruling that allows unlimited corporate contributions to political causes.

The former secretary of state, first lady and 2008 presidential hopeful — who's weighing another run at the White House — was asked during a Facebook question-and-answer session whether she'd support such a measure to overturn the high court's Citizens United decision, and put a limit on the amount corporations and unions can pour into political campaigns.

"I would consider supporting an amendment along these lines," Clinton wrote back. "That would prevent the abuse of our political system by excessive amounts of money if there is no other way to deal with the Citizens United decision."

Her position puts her in a possibly awkward spot: a super-political action committee backing her for president has collected $2.5 million in the past three months,Bloomberg reported last week.

The Ready for Hillary super-PAC has said it's collected donations from 90,000 supporters since the organization started in January 2013.CNN reported that some of Clinton's big donors from 2008 are also ready to dig deep should she decide to run.

"You have to play the game with the rules as they are," Priorities USA, a group that plans to raise money to support Clinton if she runs, told CNN. "We can't unilaterally disarm."

Clinton conducted her Facebook Q&A at the company's Menlo Park, Calif., headquarters.
She answered more than a dozen questions, including on the big stories of the day, including violence in the Middle East, saying that she hoped "there can can be a cease-fire soon to end the conflict" and that she was "fully supportive" of Secretary of State John Kerry's traveling to Egypt to possibly help broker a deal.

She called for stricter sanctions on Russia in the wake of the shoot-down of a Malaysia Airlines passenger jet in eastern Ukraine; the United States has alleged Russian-backed separatists carried out the attack.

"We should work to bring our European allies together with us on tougher sanctions that would make it clear to [Russian President Vladimir] Putin that there is a price to pay for this kind of behavior, and we should encourage Europeans to start immediately to make sure they are less dependent on Russian energy so they are not intimidated," Clinton said, The Hill reported.

Clinton gushed that she could "hardly wait" to be a grandmother, and would make "Goodnight Moon" the first book she'd read to daughter Chelsea's baby.

She also wrote that a first step as president — should she run and win — would be to "grow the economy, increase upward mobility, and decrease inequality."

As for future plans, she declared only that "I love New Hampshire," the first-in-the-nation primary state.
